Tampa Bay had a direct flyover of the International Space Station tonight. If the weather cooperates, I always try to take pics of it. I used my 10" Orion Dobsonian telescope with a camera adapter for my Nikon D7100. This combination is good enough to pick out details on the ISS like the main living quarters, solar arrays and even docking Soyuz spacecraft if they're attached. I manually track the the scope through my telescope's viewfinder - there are crosshairs that I line up with the ISS then snap away with a remote shutter trigger. About half the shots come up out of frame and only a few are in focus enough to use.
